Reference Request: Original $\Gamma$-convergence Paper Does anyone know what the original paper/work of Ennio de Giorgi, where $\Gamma$-convergence first appeared is?

I think that the first one was

_"Convergenza di alcune successioni d'integrali del tipo dell'area._ "

published in a series of papers dedicated to Mauro Picone on the occasion of his ninetieth birthday. It appeared in

_Rendiconti di Matematica e delle sue Applicazioni (6) 8 (1975), pp. 277–294_
